v0.8.26

Release Notes

Upgrade react-markdown to 10.1.0

• Reflex Markdown TLC by @masenf in #6085

Behavior Change: functions in component_map will now be passed either a bare string or a list of strings mixed with react element objects. This should only be noticeable if your component map function is attempting to manipulate the children in some way, which is not recommended. For best results, pass all args received by the component function directly to the primary rendered component.

Shared/Linked State

You can use rx.SharedState to define state that is shared among multiple frontends.
